To answer your questions based on the data provided:
-
The person doing the most jumping jacks per minute: Katrina
(You can calculate the jumping jacks per minute by dividing the number of jumping jacks by the time in minutes for each individual and comparing.) -
The person that did the most jumping jacks initially before the time started: Katrina
(Since Katrina's initial value is assumed to be more than Kimberly’s in terms of the numbers given, she would be the one with more jumping jacks at an earlier time.) -
The person showing a proportional relationship between time and # of jumping jacks: Katrina
(A proportional relationship means that as time increases, the number of jumping jacks increases at a constant rate. Analyzing the data shows that Katrina’s jumping jacks increase in a way that can be described by a linear function, while Kimberly's does not seem to be strictly linear based on the data points given.)
You can insert these responses in their respective inputs.
